Issue: DECLARE-TYPE-FREE (Version 1)

[Eric Benson <eb@lucid.com>]

For current practice:

Lucid implements DECLARE-TYPE-FREE:ALLOW already.  The production mode
of the compiler gives a warning that this usage is an extension to
Common Lisp.  The interpreter and the development mode of the compiler
don't pay any attention to declarations except SPECIAL, INLINE and
NOTINLINE.
